Built from white aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, cool cutting action suited to soft carbon steels, tool steels, and super alloys. The 38A series specification reflects a semi-friable grain structure that self-sharpens under load, maintaining cut rate and surface finish throughout the wheel's life. At 46 grit with a G hardness code (coarse, soft grade), the wheel removes material aggressively while minimizing heat buildup at the workpiece. Rated to 3600 RPM maximum operating speed.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and job-shop environments. Its 7-inch diameter and 1-inch-and-a-quarter bore fit standard spindle configurations commonly found on horizontal-spindle reciprocating-table surface grinders. Typical applications include grinding soft carbon steels, high-speed tool steels, and super alloys where a free-cutting, low-heat abrasive is required. The porous structure of the vitrified bond aids chip clearance during wet or dry grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWhite aluminum oxide abrasive — free-cutting and semi-friable for consistent surface finish on ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure improves coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade removes stock efficiently on soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n  \u003cli\u003eG hardness (soft grade) reduces glazing and heat transfer to the workpiece\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n  \u003cli\u003eNo recess, no taper — standard Type 1 flat wheel geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuited for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-inch-and-a-quarter arbor bore accepting a 7-inch diameter Type 1 wheel rated to 3600 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWheel mounting and dressing should be performed by a qualified grinding machine operator following ANSI B11.9 and OSHA 1910.215 safety standards. Always ring-test the wheel before mounting and verify that the machine spindle speed does not exceed the 3600 RPM maximum marked on the wheel. Blotters must be used between the wheel and flanges. Power down and lock out the machine before changing wheels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-GVBEP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (flat, no recess, no taper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: G (Soft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStructure\u003c\/strong\u003e: Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Equipment\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252941323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538250957106,"sku":"66252941323","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44d25c8eaa1734edd99be352b0011638.jpg?v=1785820869","url":"https:\/\/voomisupply.com\/products\/norton-66252941323-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
